Hurray. Thanks Apress.
But can you get the source code, even if you purchase the book? I sure couldn't (and I know this is neither Heiko's fault nor yours).
Though the book seems very good so far, I am very disappointed with Apress.
I'm sure it will come right sooner or later! Watch this space and apologies in the interim!
I've been in contact with Apress and so I'm happy to say the problem is resolved. The source code examples for the book is available from the book's page (same page you linked to above).
The link to the examples is titled "Example Files" and is under "Book Extras" on the left side of the page.
Awesome!
